Health status utilities and the impact of pressure ulcers in long-term care residents in Ontario

Abstract

PurposeTo estimate health status utilities in long-term care (LTC) residents in Ontario, both with and without pressure ulcers (PUs), and to determine the impact of PU on health-related quality of life (HRQOL).MethodsA retrospective population-based study was carried out using Minimum Data Set (MDS) health assessment data among all residents in 89 LTC homes in Ontario who had a full MDS assessment between May 2004 and November 2007. The Minimum Data Set-Health Status Index (MDS-HSI) was used to measure HRQOL. A stepwise regression was used to determine the impact of PU on MDS-HSI scores.ResultsA total of 1,498 (9%) of 16,531 LTC residents had at least one stage II PU or higher. The mean ± SD MDS-HSI scores of LTC residents without PU and those with PU were 0.36 ± 0.17 and 0.26 ± 0.13, respectively (p < 0.001). Factors associated with lower MDS-HSI scores included: older age; being female; having a PU; recent hip fracture; multiple comorbid conditions; bedfast; incontinence; Changes in Health, End-stage disease and Symptoms and Signs; clinically important depression; treated with a turning/repositioning program; taking antipsychotic medications; and use of restraints.ConclusionsLTC residents with PU had slightly though statistically significantly lower HRQOL than those without PU. Comorbidity contributed substantially to the low HRQOL in these populations. Community-weighted MDS-HSI utilities for LTC residents are useful for cost-effectiveness analyses and help guide health policy development.
